, r l This invention appertains to novel and useful improvements indevices for fastening sheet metal sections to a building or providing aroof thereon.

An object of this invention is to efficaciously clamp roof sections on abuilding structure in such a manner as to substantially obviate thesections becoming loose due to rain, wind and e the like.

Another object of this invention is to provide means for carrying outthe above mentioned function.

Another purpose of this invention is to provide improved clamping meansengageable with the flanges of sheet roofing which project to theinterior of a building.

Another purpose of this invention is to provide a device of the natureto be described which is extremely simple, inexpensive and easilymanufactured.

'Other objects and features of novelty will become apparent to thoseskilled in the art, in

"following the description of the illustrated pre- 'ferred embodiment ofthe present invention, illustrated in the accompanying drawings,wherein:

Figure 1 is a fragmentary perspective view of a roof utilizing thepresent invention;

' Figure 2 is a perspective view of the roof and building framingutilized beneath the roofing disclosed in Figure 1;

2 Claims. (Cl. 10813) device for the purpose of eflicaciously scaling abarn, animal house, etc. from the weather. Heretofore metallic roof topswere applied to such structures by means of nails, driving the nailsdirectly through the exposed surface of the roof sections and into theWood structural members. The necessary consequence followed; windentered the building and gradually lifted the roof a small amount untilthe roof sections rattled 10 and even blew off in times of storms.

It is well known that after a short time, the

roof sections which are secured to abuilding structure through theutility of nails, become loose to such an extent as to permit water toseep around the nails and undesirably enter the building structure.

Noting Figure 1 it is seen that no nails'are required in the attachmentof.the sections to a building structure. More important, there are nonails extending through the upper surface of the roof sections wherebyrain water and the like may penetrate the roof. It will be seen furtherthat fastening means project from the upper surfaces of each roofsection, to a point below predetermined structural members for anchoringpurposes.

A building structure I0 is provided with a plurality of purlins l2 and Mrespectively which are secured to the truss members It and I8respectively by any suitable conventional means. The

said strips l2 and M are spaced a fixed predetermined distance acrossfor a purpose to be described hereinafter.

Sheets of metallic roofing 20 are provided with a flange 22 having adoubled back portion 24 operatively associated therewith. A

Of course, sheets of roofing material 20 are placed in side by siderelation and a housing 26 is attached to a single sheet and the nextadja- 40 cent sheet. The said housing is preferablysomewhat ellipticalin cross sectional appearance and has a flange 28 on each inner portionthereof. The said flanges 28 are positioned in the above describedflange 22 and the utility of the turned down portion 24 is now apparent.

It is to be noted at this point that there is disclosed a roof utilizingsheets of material having the general wavey configuration. However, thisinvention may be utilized in conjunction with many types of sheetroofing with equal effectiveness. The said housing 26 has bowed portions30 therein which may serve the purpose of a I resilient clip when fixedto sheets of roof material. .The said housing 26 may be placed in.progressive rotation relative to each other for effecting greaterlength., A terminal portion of the housing 26 is undercut a, smallvamount, .re-

moving a portion of the bowed portion 30 and the flanges 22. Theresulting tongue 3| on the upper part of the housing 26 then becomessomewhat resilient due to the inherent properties of the metal. The nextadjacent housing may then be simply slipped under the tongue 3| as shownin Figure 10. This forms a'lap joint substantially weather resistantconnection.

A specially designed clip is used in attaching the sheets of roofing tothe building structure seen in Figure 2. A plate 32 having slots 34 and36 therein is provided with an externally threaded shank 38. An apertureis provided in the said shank 38 and a wing nut 40 with an associatedwasher 42 is adapted to be positioned on the said externally threadedshank. 'As is readily ap parent from an inspection of Figure 9 theplate- 32 is inserted between the purlins I2 and I4,

,.-thence-between the space. remaining between the adjacent roofsections 20. The slotsfi34 and.36

are engaged by the. flanges 22 of the said roof "of roofing havingupwardly extending downtightening the said wing nut the roof may ef-.flcaciously be pulled toward the purlins thereby tightly locking theroof to the building structure. Of course, the aperture mentioned abovemay be utilized for the purpose of locking thewing nut -in place or mayserve a second purpose to bedescribed subsequently.

-Go ing.now to Figure 4 there is disclosed an- }other embodiment of thisinvention, the dis- -tinguishing feature being only in the application,

of a clip 44 on the shank. Theaforementioned aperture is obviated inthis embodiment. As is the like. An aperture is supplied in the clipsand .the shank extends therethrough. -Of course, a

nut and associated washer may be used to hold the clip in place.

Noting now Figure 3 it is readily apparent that a slightly modifieddevice is utilized in securing the terminal portions of the roofsections at the apex of the said roof structure 10. strip 48 is suppliedadjacent th apex of the said A bracing building structure I 0. The plate50 of. the'said fastening means is somewhat similar to the-plate'32described above. The slots 52 therein are supplied at an anglerelative to the shank 54 of the :fastening means, as opposed to asubstantially parallel slot 34 and 36. Suitable securing means such as anut 56 and an associated washer is supplied on the said shank. vReference is now made to Figure 11 wherein there is disclosed the use ofa modified form of "the crown securing means. In place of the bracingstrip 48 there. is used a metallic anchor member 51 having properlyinclined faces for firm seating and securing purposes.

It will be noted that the housing or crown portion 58 supplied on thesaid roofing sheets 20 is somewhat different from that housing utilizedalong the longitudinal axes of the said'plane of I the roof. Thediiierence is quite evident in that the flanges are lacking. Going nowto an embodiment of the invention disclosed in Figure 6, it will benoted that the plate 32 is supplied with the shank 38 accompanied by theaperture BIlmentioned :in conjunction with the embodiment of theinvention '01 the invention.

4 shown in Figure 9. This aperture may be utilized for extending acotter pin or the like therethrough or if desired, may be utilized forreceiving a nail 62 extending therethrough. For this constructionreference is made primarily to Figure 8.

While there has been described and illustrated but preferred embodimentsof the present invention, it is apparent that variations may be madeherein without departing from the spirit Accordingly, limitation issought only in accordance with the scope of the following claims.

Having described the invention, what is claimed asnewis:
